XML格式转换成数组用递归操作很简单，大家可以下载附件测试
// Xml 转数组, 包括根键，忽略空元素和属性，尚有重大错误 public function xml_to_array( $xml ) { $reg = "/]*?>([\\x00-\\xFF]*?)/"; if(preg_match_all($reg, $xml, $matches)) { $count = count($matches[0]); $arr = array(); for($i = 0; $i { $key = $matches[1][$i]; $val = $this->xml_to_array( $matches[2][$i] ); // 递归 if(array_key_exists($key, $arr)) { if(is_array($arr[$key])) { if(!array_key_exists(0,$arr[$key])) { $arr[$key] = array($arr[$key]); } }else{ $arr[$key] = array($arr[$key]); } $arr[$key][] = $val; }else{ $arr[$key] = $val; } } return $arr; }else{ return $xml; } } // Xml 转数组, 不包括根键 public function xmltoarray( $xml ) { $arr = $this->xml_to_array($xml); $key = array_keys($arr); return $arr[$key[0]]; }第二种方法，预防递归溢出class XML { public $parser = NULL; public $document = NULL; public $parent = NULL; public $stack = NULL; public $last_opened_tag = NULL; public function XML( ) { $this->parser = xml_parser_create( ); xml_parser_set_option( $this->parser, XML_OPTION_CASE_FOLDING, false ); xml_set_object( $this->parser, $this ); xml_set_element_handler( $this->parser, "open", "close" ); xml_set_character_data_handler( $this->parser, "data" ); } public function destruct( ) { xml_parser_free( $this->parser ); } public function &parse( &$data ) { $this->document = array( ); $this->stack = array( ); $this->parent =& $this->document; $parsedata = xml_parse( $this->parser, $data, true ) ? $this->document : NULL; return $parsedata; } public function open( &$parser, $tag, $attributes ) { $this->data = ""; $this->last_opened_tag = $tag; if ( is_array( $this->parent ) && array_key_exists( $tag, $this->parent ) ) { if ( is_array( $this->parent[$tag] ) && array_key_exists( 0, $this->parent[$tag] ) ) { $key = count_numeric_items( $this->parent[$tag] ); } else { if ( array_key_exists( "{$tag} attr", $this->parent ) ) { $arr = array( "0 attr" => $this->parent["{$tag} attr"], $this->parent[$tag] ); unset( $this->parent["{$tag} attr"] ); } else { $arr = array( $this->parent[$tag] ); } $this->parent[$tag] =& $arr; $key = 1; } $this->parent =& $this->parent[$tag]; } else { $key = $tag; } if ( $attributes ) { $this->parent["{$key} attr"] = $attributes; } $this->parent =& $this->parent[$key]; $this->stack[] =& $this->parent; } public function data( &$parser, $data ) { if ( $this->last_opened_tag != NULL ) { $this->data .= $data; } } public function close( &$parser, $tag ) { if ( $this->last_opened_tag == $tag ) { $this->parent = $this->data; $this->last_opened_tag = NULL; } array_pop( $this->stack ); if ( $this->stack ) { $this->parent =& $this->stack[count( $this->stack ) - 1]; } } } function &XML_unserialize( &$xml ) { $xml_parser = new XML( ); $data =& $xml_parser->parse( $xml ); $xml_parser->destruct( ); return $data; } function &XML_serialize( &$data, $level = 0, $prior_key = NULL ) { if ( $level == 0 ) { ob_start( ); echo "<?xml version=\"1.0\" ?>"; echo "\n"; } while ( list( $key, $value ) = each( $data ) ) { if ( !strpos( $key, " attr" ) ) { if ( is_array( $value ) && array_key_exists( 0, $value ) ) { xml_serialize( $value, $level, $key ); } else { $tag = $prior_key ? $prior_key : $key; echo str_repeat( "\t", $level ); echo " echo $tag; if ( array_key_exists( "{$key} attr", $data ) ) { while ( list( $attr_name, $attr_value ) = each( $data["{$key} attr"] ) ) { echo " "; echo $attr_name; echo "=\""; echo htmlspecialchars( $attr_value ); echo "\""; } reset( $data["{$key} attr"] ); } if ( is_null( $value ) ) { echo " />\n"; } else if ( !is_array( $value ) ) { echo ">"; echo htmlspecialchars( $value ); echo "{$tag}>\n"; } else { echo ">\n"; echo xml_serialize( $value, $level + 1 ); echo str_repeat( "\t", $level ); echo "{$tag}>\n"; } } } } reset( $data ); if ( $level == 0 ) { $str =& ob_get_contents( ); ob_end_clean( ); return $str; } } function count_numeric_items( &$array ) { return is_array( $array ) ? count( array_filter( array_keys( $array ), "is_numeric" ) ) : 0; }
